Why Tech Companies Still Need IPv4 Addresses & How to Get Them

Rapid growth in technology-driven businesses means more customers, more employees, and, inevitably, more connected devices and services. This surge in connectivity requires an increased number of IP addresses, and despite the introduction of IPv6, most organizations still rely heavily on IPv4 for their networks.

In this blog, we’ll explore why growing tech companies must prioritize securing sufficient IPv4 addresses and discuss the best strategies for acquiring these increasingly scarce resources.

Why IPv4 Remains Essential for Tech Companies

1. Compatibility and Legacy Systems

IPv4 remains the backbone of today’s global internet infrastructure, widely supported by existing network equipment, software applications, and services. For rapidly growing tech businesses, ensuring compatibility with legacy customer infrastructure and third-party services is critical. IPv4 addresses offer universal connectivity, enabling seamless integration across a wide range of platforms and services.

2. Customer Reach and Reliability

Most end-user devices, home networks, and existing cloud services primarily operate on IPv4. As your tech company scales, reliable connectivity to the widest possible audience is essential. IPv4 remains the dominant protocol, ensuring maximum reach, seamless customer experiences, and minimal disruptions.

3. Compliance and Regulatory Requirements

Certain industries—including finance, healthcare, and government contracting—often mandate IPv4 address assignments or legacy protocol compatibility to meet regulatory standards or contractual obligations. Growing companies in these sectors need sufficient IPv4 allocations to comply with industry standards and customer requirements.

Strategies to Secure IPv4 Addresses for Your Growing Company

Given the ongoing IPv4 address scarcity, tech companies need to proactively manage their IPv4 resources. Here are three effective ways to secure IPv4 addresses today:

1. Purchasing IPv4 Addresses on the Secondary Market

As IPv4 addresses are no longer readily available from Regional Internet Registries (RIRs), tech companies increasingly rely on the IPv4 secondary market. Organizations can buy IP addresses directly from companies that no longer need them, ensuring secure, compliant, and reliable address space for continued growth.

Working with an experienced IPv4 broker simplifies the process. Brokers like IPTrading provide guidance on market pricing, assist with RIR compliance, and ensure transactions are conducted securely and transparently.

2. Leasing IPv4 Address Space

Leasing IPv4 addresses offers an attractive alternative, especially for startups and fast-growing businesses looking for immediate address availability without high upfront capital expenditure. Leasing arrangements provide flexibility, helping companies scale IP resources in line with growth demands, market conditions, and short-term needs.

IPv4 leasing is ideal for tech companies experiencing rapid growth, temporary projects, or uncertain long-term address requirements.

3. Optimizing Existing IP Resources

Tech companies should regularly audit and optimize their existing IP address usage. By reclaiming unused or inefficiently allocated IPv4 addresses, businesses can maximize their current IP allocations and postpone additional investments. Effective IP address management (IPAM) tools can simplify this process, ensuring addresses are allocated efficiently and preventing unnecessary expenditures.

Planning for the Future: IPv6 Adoption

While IPv4 remains essential, forward-looking tech companies should also consider their long-term strategy. IPv6 adoption is slowly but steadily increasing, and planning for eventual IPv6 compatibility can help ensure your company’s infrastructure remains robust and future-proof.

Adopting a dual-stack strategy, where networks simultaneously support IPv4 and IPv6, positions your business to manage both immediate demands and future scalability effectively.
